Abstract: An evaluation system is disclosed herein for analyzing, displaying and feedback of digital signals derived from a source of analog motion and analog force. The system includes sensors for detecting physical movement following a point-by-point measurement procedure and a digital signal generator for introducing the sensed motion and force signals to a Fourier measuring unit for analysis. Separate analysis circuits for motion characteristics and force or load characteristics from the derived signals are employed for discrete measurement. The resultant measurements and/or values are introduced to a comparator network where the measurements and/or values are compared with stored individual data and to stored universal standards. A display device such as a video monitor, visual or auditory device receives the result's of the compared motion and force measurements and values.
